The invention relates to the technical field of fiber-reactive dyestuffs.

The practice of dyeing using reactive dyestuffs has recently led to increased requirements being imposed on the quality of the dyeings and the efficiency of the dyeing process. There consequently continues to be a need for novel reactive dyestuffs which have improved properties, not only in respect of the fastnesses but also in respect of a high degree of fixing on the material to be dyed.

Fiber-reactive dyestuffs which contain an s-triazine radical to which a fiber-reactive group from the vinylsulfone series is bonded and in which the third substituent is an optionally substituted amino group or a methoxy group are thus known from U.S. Pat. No. 4,740,592 and from the Japanese Patent publications Sho-40-17113 and Sho-50-31566. Dyestuffs which contain a 2-chloro-4-cyanamido-s-triazin-6-ylamino radical are furthermore known from U.S. Pat. No. 3,758,470. However, the known dyestuffs have certain technological deficiencies; thus, they have a degree of fixing which is no longer completely satisfactory from today's standpoint, and they produce dyeings which do not have an adequate coloristic depth of color.

Novel water-soluble dyestuffs which have been improved in this respect have now been discovered with the present invention, these dyestuffs corresponding to the following formula (1) ##STR3## In formula (1): F is the radical of a monoazo, disazo or polyazo dyestuff or of a heavy metal complex azo dyestuff derived therefrom, or of an anthraquinone, phthalocyanine, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthene, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dyestuff;

The present invention furthermore relates to processes for the preparation of the dyestuffs of the formula (1) according to the invention. They can be prepared in a manner which is customary per se by routes analogous to known synthesis routes specific for the particular class of dyestuff, by reacting the typical precursors for the particular dyestuff, at least one of which contains a group of the formula (3), with one another, or by starting from a starting compound containing amino groups, of the formula (55) ##STR9## in which F, R^(x) and n have the abovementioned meanings, and reacting this with a trihalo-s-triazine of the formula (56) ##STR10## in which Hal is a halogen atom, such as, in particular, a chlorine or fluorine atom, with cyanamide or an alkali metal salt thereof and with an amine of the formula H-Q, where Q has the abovementioned meaning, in stoichiometric amounts in any desired sequence, and if appropriate subsequently carrying out further necessary conversion reactions which are familiar to the expert.

In particular, the dyestuffs according to the invention can be prepared according to the invention by reacting a compound corresponding to the formula (57) ##STR11## in which R, R^(x) and n have the abovementioned meanings and Hal is a halogen atom, such as, in particular, a chlorine or fluorine atom, with cyanamide or an alkali metal salt thereof, and reacting the resulting compound of the formula (58) ##STR12## in which F, R^(x) and Hal have the abovementioned meanings, with an amine of the formula H-Q, where Q has the abovementioned meaning, or reacting a compound of the formula (59) ##STR13## in which F, R^(x), Hal, Q and n have the abovementioned meanings, with cyanamide or an alkali metal salt thereof, or reacting a compound of the formula (55) with a compound of the formula (60) ##STR14## where Hal and Q have the abovementioned meaning.

The reaction of a starting compound of the formula (58) with the amine of the formula H-Q is carried out in an aqueous or aqueous-organic medium in suspension or solution at a temperature between 30° and 100° C., preferably between 65° and 85° C., and at a pH between 3 and 11.5, preferably between 3.5 and 7. If the reaction is carried out in an aqueous-organic medium, the organic medium is, for example, acetone, dimethylformamide or N-methyl-pyrrolidone. The hydrogen halide liberated during the condensation is advantageously neutralized continuously by addition of aqueous alkali metal hydroxides, carbonates or bicarbonates.

The reaction of an abovementioned starting compound of the formula (57) with an amine of the formula H-Q is likewise carried out like the abovementioned reaction of the compound (58) with the amine H-Q in an aqueous or aqueous-organic medium in suspension or solution, a temperature of between 15° and 70° C., preferably between 25° and 45° C., and a pH between 3 and 11.5, preferably between 3.5 and 7, being maintained here.

The starting compounds of the formula (59) can be prepared, for example, by reacting, analogously to known procedures, a compound of the formula (57) with an amine of the formula H-Q, where Q has the abovementioned meaning, or reacting a compound of the formula (62) ##STR36## in which Hal and Q have the abovementioned meanings, with a starting compound of the formula (55).

This o,o'-dihydroxy-azo starting compound corresponding to the formula (1) is then reacted in a customary and known procedure with an agent which donates a heavy metal ion, such as, for example, copper chloride, copper sulfate, chromium chloride, chromium sulfate and cobalt chloride, to give the heavy metal complex azo dyestuff according to the invention.

According to the invention, the dyestuffs according to the invention can also be prepared starting from one or more starting substances containing a β-hydroxyethylsulfonyl group, such as from an amine of the formula H-Q, where Q has the abovementioned meaning, but with the difference that the group(s) of the formula --SO₂ --Y are β-hydroxyethylsulfonyl groups, by first preparing, analogously to the abovementioned procedures according to the invention, a starting compound which corresponds to the formula (1) with the meaning given, but with the difference that the group(s) --SO₂ --Y are β-hydroxyethylsulfonyl groups, and converting the β-hydroxyethylsulfonyl groups in this starting compound into other groups --SO₂ --Y corresponding to the compound (1) according to the invention analogously to known procedures, thus, for example, into ester derivatives thereof, such as, for example, of polybasic inorganic acids or of aliphatic and aromatic carboxylic or sulfonic acids, thus, for example, into compounds in which Y is the β-chloroethyl, β-sulfatoethyl, β-phosphatoethyl, β-thiosulfatoethyl, β-acetoxyethyl or β-toluylsulfonyloxyethyl group. Examples of esterifying and acylating agents which are suitable for this are the corresponding inorganic or organic acids or anhydrides or halides or amides thereof, such as, for example, sulfuric acid, sulfuric acid containing sulfur trioxide, chlorosulfonic acid, sulfamic acid, phosphoric acid, polyphosphoric acid, phosphorus oxychloride, mixtures of phosphoric acid and phosphorus pentoxide, acetic anhydride, toluenesulfonyl chloride and thionyl chloride.

The sulfation is carried out, for example, by reaction with concentrated sulfuric acid at a temperature between 0° and 20° C. or by reaction with chlorosulfonic acid in a polar organic solvent, such as, for example, N-methylpyrrolidone, at a temperature between 10° and 80° C. The sulfation is preferably carried out by introduction of the starting dyestuff containing β-hydroxyethylsulfonyl groups into sulfuric acid monohydrate at a temperature between 5° and 15° C.

Those compounds in which Y is the vinyl group can be prepared from analogous ester derivatives thereof by means of alkali, thus in an aqueous medium at a pH of 10 to 12 and a temperature between 30° and 50° C. in the course of 10 to 20 minutes. The synthesis of, for example, β-(dialkylamino)-ethylsulfonyl and β-thiosulfatoethylsulfonyl derivatives is carried out by reaction of vinylsulfonyl compounds thereof with the corresponding dialkylamine or with an alkali metal salt of thiosulfuric acid, such as sodium thiosulfate. All of these procedures of conversion of one group --SO₂ --Y into another are familiar to the expert in this fiber-reactive field and are described in numerous instances in the literature.

The dyestuffs of the formula (1) according to the invention are suitable for dyeing and printing the most diverse materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and in particular all types of fiber materials containing cellulose. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen and hemp, as well as cellulose and regenerated cellulose. The dyestuffs of the formula (1) are also suitable for dyeing or printing fibers which contain hydroxy groups and are contained in blended fabrics, for example mixtures of cotton with polyester fibers or polyamide fibers.

The dyestuffs according to the invention can be applied to the fiber material and fixed on the fiber in various ways, in particular in the form of aqueous dyestuff solutions and printing pastes. They are suitable both for the exhaust process and for dyeing by the pad-dyeing process, in which the goods are impregnated with aqueous dyestuff solutions, if appropriate containing salts, and the dyestuff is fixed, after an alkali treatment or in the presence of alkali, if appropriate under the action of heat. The dyestuffs according to the invention are particularly suitable for the so-called cold pad-batch process, in which the dyestuff is applied to the padder together with the alkali and is then fixed by storage at room temperature for several hours. After fixing, the dyeings or prints are rinsed thoroughly with cold and hot water, if appropriate with addition of a dispersing agent which promotes diffusion of the non-fixed portions.

The present invention therefore also relates to the use of the compounds of the formula (1) according to the invention for dyeing (including printing) these materials and to processes for dyeing (and printing) such materials by a procedure which is customary per se, in which a compound of the formula (1) is employed as the coloring agent, by applying the compound of the formula (1) to the material in an aqueous medium and fixing it on the material by means of heat or by means of an alkaline compound or by means of both.

If anthraquinone dyestuffs according to the invention have an inadequate solubility in the alkaline dye liquor, this deficiency can be overcome in the manner which is known from the literature by addition of dispersing agents or other non-coloring compounds, for example a naphthalenesulfonic acid-formaldehyde condensate or in particular anthraquinone-2-sulfonic acid.

The dyestuffs of the formula (1) are distinguished by a high reactivity, good fixing capacity and very good build-up capacity. They can therefore be employed by the exhaust dyeing process at low dyeing temperatures and require only short steaming times in the pad-steam process. The degrees of fixing are high and the non-fixed portions can easily be washed out, the difference between the degree of exhaustion and the degree of fixing being remarkably small, i.e. the soaping loss is very low. The dyestuffs of the formula (1) are also particularly suitable for printing, above all on cotton, and similarly also for printing nitrogen-containing fibers, for example wool or silk or blended fabrics which contain wool or silk.

The dyeings and prints produced on cellulose fiber materials with the dyestuffs according to the invention have a good depth of color and a high fiber-dyestuff bonding stability both in the acid and in the alkaline range, and furthermore good light-fastness and very good wet-fastness properties, such as fastnesses to washing, water, seawater, cross-dyeing and perspiration, as well as a good fastness to pleating, fastness to ironing and fastness to rubbing.

The following examples serve to illustrate the invention. The parts are parts by weight and the percentage data are percentages by weight, unless noted otherwise. Parts by weight bear the same relationship to parts by volume as the kilogram to the liter.

The compounds described by way of their formula in these examples are shown in the form of the free acids; they are in general prepared and isolated in the form of their alkali metal salts, such as lithium, sodium or potassium salts, and are used for dyeing in the form of their salts.

The starting compounds and components mentioned in the form of the free acid in the following examples, in particular the tabular examples, can likewise be employed in the synthesis as such or in the form of their salts, preferably alkali metal salts.

The absorption maxima (λ_(max)) in the visible range quoted for the compounds according to the invention have been determined with the aid of alkali metal salts thereof in aqueous solution. In the tabular examples, the λ_(max) values are placed in parentheses where the color shade is stated; the wavelengths are stated in nm.

It has very good fiber-reactive dyestuff properties and, when used by the processes customary for fiber-reactive dyestuffs, gives deep, brilliant scarlet red dyeings and prints having good fastness properties, of which the fastness to water and fastness to perspiration may be emphasized in particular. It is particularly distinguished by a high degree of fixing both in the exhaust processes at temperatures between 40° and 80° C. and in the cold pad-batch dyeing processes.

Example 124

48.3 parts of 1-(4'-sulfophenyl)-3-carboxy-4-(5"-amino-2"-sulfo-phenylazo)-5-pyrazolone are reacted in aqueous solution with 19 parts of cyanuric chloride at 0° to 3° C. and at a pH of 3.5 to 4. 4.4 parts of cyanamide are then added, the pH is brought to 10 by means of aqueous sodium hydroxide solution and the mixture is heated to 50° to 60° C. It is subsequently stirred at 50° to 60° C. for a further 90 to 120 minutes, the pH being kept between 9.5 and 10, and when the condensation reaction has ended aqueous hydrochloric acid is added until the pH reaches 5, 29.5 parts of 3-(βsulfatoethylsulfonyl)aniline are then added and the mixture is heated to 85° C. and further stirred until condensation reaction is complete, a pH of 3.5 to 4 being maintained.

The azo dyestuff according to the invention formed is isolated in the form of its alkali metal salt (sodium salt) by evaporation of the synthesis solution under reduced pressure or by spray drying. It has, written in the form of the free acid, the formula ##STR45## and has very good fiber-reactive dyestuff properties. When used by the known techniques, it dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, in deep, yellow shades with good fastness properties, and is distinguished by a very high fixing yield both for dyeing by the exhaust process between 40° and 80° C. and for dyeing by the cold pad-batch dyeing processes.

Example 125

18.8 parts of 1,3-diaminobenzene-4-sulfonic acid are added to a suspension of 19 parts of cyanuric chloride in 200 parts of ice-water. The mixture is stirred first at 0° to 5° C. and at a pH of 2.5 for about two hours and then at 0° to 5° C. and at a pH of 4 for about 30 minutes. 4.4 parts of cyanamide are then added, the pH is brought to 10 by means of sodium hydroxide solution, the temperature is slowing increased to 50° to 60° C. and the mixture is further stirred for about another 1.5 hours, a pH of 10 and a temperature of 50° to 60° C. being maintained. The pH is then brought to 7 by means of aqueous hydrochloric acid, 20 parts by volume of an aqueous 5 N sodium nitrite solution are added diazotization is carried out by slowly adding this mixture to a mixture of 50 parts by volume of concentrated hydrochloric acid and 600 parts of ice. The mixture is subsequently stirred for about a further 2 hours and any excess of nitrous acid is destroyed in the customary manner by means of sulfamic acid.

The resulting diazonium salt suspension is then added to an aqueous solution of the sodium slat of 60 parts of 4-hydroxy-5-amino-6-[4'-(βsulfatoethylsulfonyl)-phenylazo]-naphthalene-2,7-disulfonic acid. The coupling reaction is carried out at 15° to 25° C. and at a pH of 4.5 to 5.5, 29.5 parts of 4-(β-sulfatoethylsulfonyl)-aniline are then added and the condensation reaction is carried out at 85° C. and at a pH of 3.5 to 4 for about 2 hours. The mixture is subsequently clarified with a little kieselguhr at about 40° C. and filtered and the filtrate is evaporated.

A black powder, containing electrolyte, of the alkali metal salt (sodium salt) of the diazo compound of the formula ##STR46## is obtained. It has very good fiber-reactive dyestuff properties and dyes cotton, for example, in strong navy blue shades.

Example 126

To prepare an azo dyestuff according to the invention, the procedure is in accordance with the procedure of Example 125, but instead of the 29.5 parts of 4-(β-sulfatoetylsulfonyl)-aniline in the reaction with the chlorotriazine compound, the same amount of 3-(βsulfatoethylsulfonyl)-aniline is employed.

The alkali metal salt of the disazo compound of the formula ##STR47## which, for example, dyes cotton in strong navy blue shades, is obtained.

Example 164

49 parts of 1-amino-2-sulfo-4-(3'-amino-4'-sulfo-phenyl)-amino-9,10-anthraquinone are reacted in aqueous solution with 19 parts of cyanuric chloride at 0° to 5° C. and at a pH of 3.5 to 4. 4.4 parts of cyanamide are then added, the pH is brought to 10 by means of aqueous sodium hydroxide solution and the temperature of the mixture is slowly increased to 50° to 60° C. The mixture is further stirred in this temperature range for some time, and when the condensation reaction has ended the pH is brought to 5 with aqueous hydrochloric acid, 29.5 parts of 3-(β-sulfatoethylsulfonyl)-aniline are added and the third condensation reaction is carried out at 85° C. and a pH of 3.5 to 4.

After customary clarification of the synthesis solution, the dyestuff according to the invention of the formula (written in the form of the free acid) ##STR59## is obtained as an alkali metal salt (sodium salt) by evaporation of the filtrate. It dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, for example cotton, in deep, brilliant blue shades by the application and fixing processes customary for fiber-reactive dyestuffs.

Example 165

To prepare an anthraquinone dyestuff according to the invention, the procedure is in accordance with the procedure of Example 164, but instead of 3-(β-sulfatoethylsulfonyl)-aniline, the same amount of 4-(β-sulfatoethylsulfonyl)-aniline is employed. A blue dyestuff with equally good dyeing properties, which, for example, produces deep, brilliant blue dyeing and prints on cotton, is obtained.

Example 166

To prepare an anthraquinone dyestuff according to the invention, the procedure is in accordance with the procedure of Example 164, but 49 parts of 1-amino-2-sulfo-4-(3'-amino-2',4',6'-trimethyl-5'-sulfo-phenyl)-amino-9,10-anthraquinone are employed as the starting anthraquinone compound.
